Network operators compose Service Function Chains (SFCs) by tying different network
functions (eg, packet inspection, flow shaping, network address translation) together and …

The emergence of Network Function Virtualization (NFV) and Service Function Chaining
(SFC) together enable flexible and agile network management and traffic engineering. Due …

Service Function Chains (SFCs) comprise a sequence of Network Functions (NFs) that are
typically traversed in-order by data flows. Consequently, SFC delay grows linearly with the …

By replacing traditional hardware-based middleboxes with software-based Virtual Network
Functions (VNFs) running on general-purpose servers, network function virtualization …

Network Function Virtualization (NFV) promises to reduce the capital and operational
expenditure for network operators by moving packet processing from purpose-built …

Network Function Virtualization (NFV) advocates running service function chains (SFCs) on
commodity servers as software, thereby providing a new level of flexibility to the deployment …

Network Function Virtualization (NFV) is an emerging technology, which enables service
agility, flexibility and cost reduction by replacing traditional hardware middleboxes with …

Abstract Network Function Virtualization (NFV) provides great flexibility in solving the
problem of deploying service function chains (SFCs). The existing serial SFCs organize …

In legacy networks, network functions (eg, firewalls, NAT, QoS) are highly dependent on
dedicated hardware. It is sophisticated and costly for network operators to determine the …

Network slicing has become a fundamental property for next-generation networks,
especially because an inherent part of 5G standardisation is the ability for service providers …
